linux-firmware: delink some tegra firmware to avoid pulling in full nvidia firmware

Some Nvidia firmware is shared between products but the symlinks cross
product/driver boundaries, resulting in the -nvidia-tegra package
depending on the ~150MB -nvidia-gpu package for a few 10kb files.

If we replace the symlinks with the actual content of the files then this
dependency disappears.
